Paper Title:
Dynamic Behavior of the Advanced Actuator
  Abstract

The advanced actuator is a kind of swaying mechanism specially developed for certain aircraft, having low rotational speed and great torque. Utilizing criterions of mass equivalent and bending stiffness equivalent, this paper firstly applies simplification to the actuator, getting a piece of continuous beam with varying circular sections. According to the mounting condition of actuator, then establishes the finite element dynamic analyzing model, using I-DEAS software, selecting method of synchronous vector iteration, finishes normal modal analyzing. Next, carries Hertzian contact resonance analyses to ball straight-rotary pair, ball spline pair and ball unload pair, calculates contact resonance frequencies. Considering the resistance torque being moving still concludes formulae of quantity of contact resonance frequencies. Lastly, based on load spectra, makes a conclusion that antiresonance behavior of the actuator is well, showing that the design plan is feasible. Experimentation of prototype indicates that the above theoretical analyses are correct.
